Just completed a 2003 SBS to 2011 SBS migration and almost everything is working
Old SBS was called SBSSEERVER
New SBS is called SBS2011
We have setup a CNAME in DNS to point SBSSERVER to SBS2011 which works fine with Windows 7 machines, but this will not work with XP Client which complain of a duplicate name
Any Idea's on this one.
